Rail transport in Singapore mainly consists of a passenger urban rail transit system spanning the entire city-state: a rapid transit system collectively known as the Mass Rapid Transit (MRT) system operated by the two biggest public transport operators SMRT Trains (SMRT Corporation) and SBS Transit, as well as several Light Rail Transit (LRT) rubber-tyred automated guideway transit lines also operated by both companies. In addition, local specialised light rail lines are in operation in places such as the Singapore Changi Airport and Sentosa.

A short remaining section of the railway originally built during the British colonial period is connected to the Malaysian rail network, and is operated by Malaysian railway company Keretapi Tanah Melayu (KTM). The Singapore section of the railway now serves only inter-city passenger services; until 2011 the railway also carried freight between Malaysia and the Port of Singapore at Tanjong Pagar.

Two international rail links to Malaysia have been proposed to replace the KTM railway. The Johor Bahru–Singapore Rapid Transit System is currently under construction and is scheduled to begin operations in 2026. The Kuala Lumpur–Singapore High Speed Rail was planned but shelved in January 2021.

Although Singapore is not a member of the International Union of Railways (UIC) given the nature of Singapore as a city-state and its lack of a national railway proper, SMRT Corporation, SBS Transit and the Land Transport Authority are members of the International Association of Public Transport (UITP).^[4] SMRT Corporation is also a member of the Community of Metros (CoMET) benchmarking group. In addition, Keretapi Tanah Melayu, the Malaysian train operator that operate Shuttle Tebrau services in Singapore is a member of UIC.
